Cheers, Julio
It is a pleasure to hear from you, my friend. I was almost back in New York again this May for LIRA and to visit BAS but just couldn't work it into the schedule.
Nonetheless... I was chatting with John Toddaro from BAS today and may be returning for a visit late in the year. Hope to see you again
As far as reef lamps... it is such a fast evolving technology. Do keep in mind that any "best of" list from anyone will change easily in as little as the 6-12 month picture.
With that said... and with the understanding that natural sunlight is best

...
I really like the double ended HQI lamps very well. Even as cool as 10K
For specifics... I like Iwasaki 6500Ks when growth is a primary focus.
I like 10K Aqualines or Ushios when you want good growth and a little bluer color (more attractive to most aquarists).
And I like 20K Radiums to finesse some (some... not all) tricky colors with stonies. Much more blue than needed for many corals though. You better like blue!

I do.... I'll admit it.
Of course, it is the species of coral you select that will ultimately dictate which lamp color you will want/need to emphasize. But the above is a fair generalization of my opinion.
If the question ever comes down to CRI, PAR values, lamp life, efficacy, etc (that which is beyond practical applications)... I would certainly defer to a consensus from the likes of respected folks that have done research on the subject like Sanjay Joshi and Dana Riddle (Riddle Laboratories).
Kind regards to all.
